The Budapest opera house is a beautiful Neo-Renaissance building opened in 1884. Construction included the use of marble and frescos by some of the best artisans of that era. Designed by Miklós Ybl, one of Europe's leading architects in the mid to late 19th century, the Budapest Opera House quickly became one of the most prestigious musical institutions in Europe. Many important artists performed here, including Gustav Mahler, who was also the director for three seasons.
The Budapest Opera House is considered to be amongst the best opera houses in the world in terms of its acoustics, and has an auditorium that seats 1200 people. It is horseshoe-shaped and, according to measurements done by a group of international engineers, has the third best acoustics amongst similar European venues (after the Scala in Milan and the Paris Opera House). The statue of Ferenc Erkel stands in front of the Opera House. He was the composer of the Hungarian national anthem and the first music director of the Opera. The other statue in front of the Budapest Opera is of Ferenc Liszt, the well-known Hungarian composer.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
